You cannot have a shoutbox here. WordPress.com programming strips out all javascript, iframes, forms and flash embeds for security reasons.
You can drag and drop your meebo widget into the sidebar and register with meebo. Then you will have messanging. And this will help with the set up and configuring of widgets.

WordPress.com and wordpress.org operate on different software. All wordpress blog templates from wordpress.org are free of charge. Usually if you leave here then what you would have to pay for is your hosting of the free wordpress.org blog, unless you have your own server. But I think you mean you want to stay here and blog for free with wordpress.com as your host. That what you mean, right?

P.S. If you took out a few moments and read the resources I gave you then you would know that if you had typed "shoutbox" into the forum search box you would have had the answer right away without waiting for me to tell you. ;)
